android - AsyncTask onPostExecute - 新的 Intent 错误

Question

我的 AsyncTask 类中有这段代码:

    protected void onPostExecute(Integer result) 
    {
        if (result == 1)
        {
            try {
                Global.mmOutStream.write(99);
            } catch (IOException e) { }

            Intent intentTrashcanLocation = new Intent(TrashcanLocationActivity.this, TrashcanLocationActivity.class);     
            startActivity(intentTrashcanLocation);
        }

    }

这让我在“Intent”行出错:

• 行断点:TrashcanOnWayActiity$waitarrival [line:53] - onPostExecute(Integer)
• TrashcanLocationActivity 类型的封闭实例在范围内不可访问

我想做的基本上是在我异步获得某些输入时显示下一页。我无法解决这个问题。非常感谢任何帮助!

你正在使用同一个类

Intent intentTrashcanLocation = new Intent(TrashcanLocationActivity.this,
                                           TrashcanLocationActivity.class);     
startActivity(intentTrashcanLocation);

应该是这样的

Intent intentTrashcanLocation = new Intent(TrashcanLocationActivity.this,
                                           TrashcandetailActivity.class);     
startActivity(intentTrashcanLocation);
